Australian-Armenian singer Mary-Jean O’Doherty will sing Face The Shadow in Vienna on Saturday as part of the Armenian group Genealogy.
Speaking to BBC Wales, the singer, who studied at the Cardiff International Academy of Voice, praised the Welsh support which helped the group through the semi-final on Tuesday.
“It’s just one of those surreal moments where you just think ‘wow’,” she said.
“There was a lot of Armenian flags and Welsh flags as well which was great. There was so much positive energy.”
O’Doherty, born in the United States to an Australian father and a Greek-Armenian mother, has settled in Cardiff with her Welsh husband.
She was selected for this year’s contest by the Public Television of Armenia.
“I have never been to Armenia and I have always wanted to know about my heritage, about my genealogy,” she added.
“I couldn’t think of a more interesting or outstanding way to do both.”
